Will we have to know how to calculate Heat Capacity at constant Volume and Pressure

I'm not sure but its not as bad as what the textbook makes it look like: for constant volume its 3/2R, 5/2R, or 3R for atoms linear and then nonlinear molecules. For consant pressure its 5/2R, 7/2R, or 4R.

the constants and equation sheet posted on the chem class website has Cv and Cp for ideal gasses so as long as the problem says its an ideal gas you can just use the given ones I'm pretty sure so all you'd have to know is that Cv means specific heat capacity at constant volume bc of the subscript and that R is 8.3, hope this helps!
